SIDE-DUMPING BODY FOR VEHIOLESL.

SPECIFICATION vforming part of Letters Patent N o. 726,638, dated April28, 1903.

Application iled August 27, 1902.

T0 a/ZZ whom, it may concern:

Beit known that LWILLIAM L. CHnssRowN, a citizen of the United States,and a resident of Eaton, in the county of Weld and State of Colorado,have invented a new and Improved Side-Dumping Body for Vehicles, ofwhich the following is a full, clear, and exact description.

My invention relates to an improvement ink the body or rack constructionof vehicles and the purpose of the invention is to provide a side dumpwherein the dumping will be automaticall y accomplished the moment thatsundry supports beneath the body or rack are Withdrawn, which Withdrawalat the dumping side of the body or rack is accomplished by a singlemovement of a single lever, and, further, to so construct the rack orbody that as the rack or body is restored to its normal position theside gate opened for dumping will be automatically closed.

Another purpose of the invention is to provide a construction of aside-dumping body or rack which will be simple, durable, eco-l nomic,and practical, automatic, and capable of being used on any wagon-gear,which con-I struction of body or rack is especially adapted for haulingsugar-beets, but which may be adapted for all purposes of a farm andupon any vehicle wherein material istobe hauled and dumped, includingrailroad-cars.

The invention consists in the novel vconstruction and combination ofthev several parts, as will be hereinafter fully setfort-h, and pointedout in the claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a 'side elevation of thevehicle body or rack having theimprovementapplied, thecarrying-section being in normal position. Fig. 2is an end view of thevehicle body or rack, the carrying-section beingalso shown in normal position. Fig. 3 is a sectional end elevation ofthe body or rack, showing the carrying-section in dumping position. Fig.

Fig. 6 is anenlarged side elevation of the lever-controlled means for operating theside gates of the carrying-section. Fig. 7 is a detail sectional viewshowing the application ofthe dumping-lever to a side gate of thecarrying-section of the body or rack, the said section being practicallyonthe line 7 7 of Fig. 6. Fig. Sis a vertical section takensubstantially on the line 8 A8 of Fig. 2, and Fig. 9 is a detailperspective View of one of the bearing-blocks for the carryingsection ofthe body or rack. 1

The device consists, primarily, of a basesection A and a carryingectionB.. The basesection consists of pairs of longitudinal side beams 10,connected at their bottom portions at suitable intervals apart bycross-bars 11.. Transverse supporting-beams 12 are made to rest on theside beams 10, the transverse beams 12 being of any suitable dimensions,

and the side beams lO are attached to the bottom cross-bars 11 throughthe medium of rods 13 in the form of clips.

At the central portion of each transverse beam 12 a bearing-block 14 issupported, the said bearing-blocks being provided with longitudinalchannels 15 in their under surfaces, so that the said bearing-blocks maystraddle the transverse beams 12. Clips 16 are elnployed to hold thebearing-blocks on the transverse beams 12, the upper portions 17 ofwhich clips are bifurcated, so that the upper portions of the clips maypass over the bearing-blocks at each side of their centers, as is shownin Figs. 2, 3, and 4. Each bearing-block 14 at its upper centrallportion is provided with a trunnion 18, which trunnions extend inhorizontal alinement from the side portions of the blocks, as is bestshown in Fig. 9. l

In the spaces between the longitudinal side beamsA 10 of thebase-section A supportingbars 19 are pivoted at their lower ends, as isbest shown in Fig. 5. These su pporting-bars are adapted to assume theinclined position shown in Fig. 5 or the perpendicular position shown inFig. 1. -The supporting bars or standards 19 at each side of thebase-section A are connected by a link 20, and at one end of each linkone end of a spring 21 is secured,and theopposite ends ofthe saidsprings are att-ached to either one or the other of the pair oflongitudinal side beams 10. At the opposite end of each link 20 a lever22 is pivotally attached, and the lower ends of these levers aresuitably fulcru med upon projecting arms 23 from an end of thebase-section A, as is illustrated in Figs. 1 and 5.

The carrying-section B of the body or rack may be of any suitable size,and consists of end sections 24, a bottom section 26, and side sections25, which are hinged to the bottom section, as is shown in Figs. 3 and4. These side sections 25 constitute side gates for the saidcarrying-section B, and when dropped down flush with the bottom 26permit the contents of the carryingsection to pass out at the open sidewhen the said carrying-section is inclined in direction of such side oris brought to thedumpingposition. (Illustrated in Figs. 3 and 4.)

Transverse beams 27 are arranged, preferably in pairs, at the undersurface of the bottom 26, as is shown in Fig. 1, a pair of suchtransverse beams 27 being also at each end 'tween the said slats orplates and the end sections 24, in which chambers 29 pulleys 30 aremounted to turn, and the end sect-ions or plates 29 preferably extenddown below the bottom 26 of the carrying-section, as is illustrated inthe drawings.

At the central portion of each transverse beam 27 of thecarrying-section B of the Vehicle body or rack a block 31 is secured,and these blocks are preferably slotted or have channels produced intheir upper portions, whereby they may straddle the transverse beams 27,and each block 31 is provided with a suitable opening to receive atrunnion 18 of a bearing-block 14. Through this connection between thebearing-blocks 14 and the blocks 3l of the carrying-section thecarrying-section is centrally and pivotally mounted upon thebase-section A.

Suitable braces 32 are attached to the downwardly-projecting portionsof'the plates or laths 28 and to the bottom 26 of the carryingsection.Side braces 33 are also employed, which side braces are attached to thebottom portion of the base-section A and are connected with the innerblocks 3l of the under set of blocks, as is shown in Fig. 1, turnbuckles34 being located between the points of attachment with the base-sectionA and the attachment of said braces with the carrying-section, so thatthese braces need in no manner interfere with the dumping action of thecarrying-section, yet add materiali)T to the strength of saidcarrying-section.

At each end of the carrying-section B of the vehicle body or rack twohorizontal lengths of chain 35 and 35a are secured at one of their endsto the end portions of the side gates 25, as is best shown in Figs. 2and 3, and the lengths of chain 35 and 35 at each end of saidcarrying-section are connected by a spring 36 of suitable strength,which springs serve to draw the side gates from their lower or dumpingposition to their upper or closed position and retain such side gates insuch position when used in connection with elbowlevers 38 and 38,pivoted one at each side of the center at each end ofthecarrying-section, and the upright members of. the elbow-levers 38 and38a normally engage with the outer surfaces ot' buttons 37, located onor formed integral with the lengths of chain 35 and 35, where theyconnect with lthe springs 36, the upper ends of the said elbow-levers 38and 38a being downwardly and outwardly beveled.

Each elbow-lever 38 is pivotally connected with the upper end of a link39, while the elbow-levers-38n are similarly connected with links 39a.These links at their lower portions cross each other at the ends of thebody or rack and are pivotally attached to the end transverse beams 12of the base-section A at each side of the center of such beams, as isshown also in Figs. 2 and 3.

When the carrying-section B of the body or rack is in its horizontal ornormal position, (shown in Figs. 1 and 2,) itis supported in suchposition by means of the supporting-bars 19, which are thenwperpendicular, as is shown in Fig. 1, and are in engagement with theunder faces of wear-plates 40, secured to the under surface of thebottom of the carrying-sections B, the said wear-plates being providedwith suitable longitudinal guide-ribs 40, although these ribs may beomitted, if desired. When the load is to be dumped, the lever 22 at thatside at which the dumping is to be accomplished is drawn downward, as isshown in Fig. 5, thus carrying the su pporting-bars 19 at said side tothe inclined position, (shownin Fig. 5,) whereupon the weight of thematerial in the carrying-section B will tend toward the nnsupported sideof the carrying-section, causing said side to assumeadownwardly-inclinedposition, (shown in Figs. 3 and 4,) and likewise cause one of theelbow-levers-the elbowlever 38a, for example, which is near the inclinedsideto be carried away from the buttons 37, whereas the opposingelbow-levers 38 will be drawn in direction of the inclined side, wherebythe elbow-levers 38a permit the springs 36 to extend, and consequentlypermit the side gate at the lower side of the carrying-section to drop,while the opposing elbow-levers 38 maintain their positions at the lugsor buttons 37, adjacent to the elevated side of the carrying-section,thus holding the side gate at that side closed. This movement of theelbow-levers is brought about by the movement of the links 39a incidentto the inclined position of the carrying-section A.

After theload has been dumped the springs IIO sus

36 willagain contract to close the dropped side gate, and thecarrying-section of the Vehicle body or rack being-simply pivoted willnormally assume itshorizontal position, at which time the pivotedsupporting-barslQ are again restored to their vertical positions. Whenthe carrying-section B of the body orv rack is carried to its dumpingposition, it is held in such position until the dropped side gate iselevated by means of latches 41, which are pivoted in suitable bearings42 at the unt der central portions of the carrying-section B, as whenthe carryingsection B is inclined the latch 4l at the inclined side willengage of the carrying-section B, one of the said posts being at eachside of said section, and when the side gate at the lower portion of thecarrying-section drops to a dumping position the head 44.0ftheprojecting post 45 at that side of the carrying-section will extendover the pivot portion of the latch 4l; but as the side gate is broughtto its upper position the head 44 from the post 45 in action will pressupon the pivoted end of the latch 4l in actionand carry said latch outof engagement with its keeper 43, thereby permitting the carryingsectionB to resume its horizontal or normal position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- Y l. A dumping carrying-sectio n,a base-section onwhich the carrying-section is p'ivotally mounted, side gates adaptedV todrop, and' means for automatically opening one side gate and holding theother side gate closed, which means are operated through the movement ofthe carrying-section upon the base-section, as
